Bug Description

I found this patch:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77f07800cb456bed6e5c345e6e4e83e8eda62437

After patching my kernel (3.13.0-29) with this, the sound is working great!

Please include this patch in the next Ubuntu kernel. :-)

Kind regards from Norway.

Patching the linux kernel also worked for me on Ubuntu 12.04 on an ASUS Z97-Pro Motherboard.

For those who don't know how to install the latest linux kernel (as well as resolve other hardware compatibility issues on the Z97 chipset), I wrote some instructions here:
